32 | Description:\r |
33 | \r |
34 | This function makes boot time changes to the contents of the\r |
35 | MiscSystemManufacturer (Type 13).\r |
36 | \r |
37 | Parameters:\r |
38 | \r |
39 | RecordType\r |
40 | Type of record to be processed from the Data Table.\r |
41 | mMiscSubclassDataTable[].RecordType\r |
42 | \r |
43 | RecordLen\r |
44 | Size of static RecordData from the Data Table.\r |
45 | mMiscSubclassDataTable[].RecordLen\r |
46 | \r |
47 | RecordData\r |
48 | Pointer to copy of RecordData from the Data Table. Changes made\r |
49 | to this copy will be written to the Data Hub but will not alter\r |
50 | the contents of the static Data Table.\r |
51 | \r |
52 | LogRecordData\r |
53 | Set *LogRecordData to TRUE to log RecordData to Data Hub.\r |
54 | Set *LogRecordData to FALSE when there is no more data to log.\r |
55 | \r |
56 | Returns:\r |
57 | \r |
58 | EFI_SUCCESS\r |
59 | All parameters were valid and *RecordData and *LogRecordData have\r |
60 | been set.\r |
